I was thinking of creating a watch with world time rings, similar but not the same as the attached image, as there is no functionality option with Facer is it possible to have a working version that granted may only work in UK but will show world time at a glance. Posting this for a general discussion on the topic and would welcome all input and suggestion
Please walk me through this as I’m being really thick, I agree with rotating disc, i’m going to have 24 short names, running clockwise from London each name is +1 hour consecutively, anti-clockwise from LON each name is -1 hour consecutively. What parameter (TAGS) do I apply to the ring?
Not one, you will have to create a code for it.
Since we can assume that minutes and seconds will be the same in all those countries it will be easier.
Thake current time in hours (24 not 12 formats of course) and subtract from it current UTC time in hours.
Then divide it by 24 and multiply by 360 (this will give you rotation angle).
You might need to tweak it a bit (eg.: by adding additional rotation to calibrate its position) and make sure that it rotates in the right way.
When you have a normal 24 hour, analog face it shows 12 on top, 24 on the bottom, 18 on the right and 6 on the left (+ other ones between). If +x and -x would move with hour hand it would mean that either your timezone is changing (vs those cities you listed), or that timezones in those cities are changing.
Everyone is living in a time zone (for me it is now +2 UTC (+1 for Poland and +1 for summer time)) so on my watch, it should show my city (or the major city in my time zone) with its time zone (+2) on top; and if someone lives in London it should show 00 on top along with LON.
Do you get it?
If not let me know what timezone are you in, I will try to explain it from your perspective.
